Yes there are lots of ways of doing this. For example if you have asp capability (running a Windows IIS box) then you can put this at the top of your asp page -
<%
Dim strWrongDomain, strCorrectDomain
strWrongDomain = "
www.mysite.com"
strCorrectDomain = "mysite.com"
If Request.ServerVariables("http_host") = strWrongDomain Then
Response.Redirect "http://" & strCorrectDomain & Request.ServerVariables("URL")
End If
%>
